Step-by-Step Instructions
-
Step 1: Preheat and Prepare Sweet Potatoes
Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish. Peel the sweet potatoes and cut them into roughly 1-inch chunks. Place the sweet potato chunks in a large pot, cover them with cold water, and bring to a boil. Cook for 15-20 minutes, or until the sweet potatoes are very tender when pierced with a fork.
Small tip: Ensure the sweet potatoes are uniformly cut so they cook evenly.
-
Step 2: Mash the Sweet Potatoes
Carefully drain the cooked sweet potatoes thoroughly. Return them to the pot or transfer them to a large mixing bowl. Mash the sweet potatoes until they are smooth and free of lumps. You can use a potato masher, a fork, or an electric mixer for the creamiest results.
-
Step 3: Mix the Base Ingredients
To the mashed sweet potatoes, add the melted butter, light brown sugar, granulated sugar, milk, lightly beaten eggs, vanilla extract, ground cinnamon, ground nutmeg, and a pinch of salt. Mix everything together until it’s well combined and the mixture is smooth and creamy. Make sure all ingredients are fully incorporated.
Small tip: Avoid overmixing after adding the eggs; just mix until everything is just combined.
-
Step 4: Assemble the Casserole Base
Pour the prepared sweet potato mixture into your greased 9×13 inch baking dish. Use a spatula to spread it evenly across the bottom of the dish. This creates a beautiful, smooth foundation for your casserole.
-
Step 5: Prepare the Pecan Crumble Topping
In a medium bowl, combine the all-purpose flour, light brown sugar, chopped pecans, and a pinch of salt. Add the cold, cubed butter to this mixture. Use your fingers or a pastry blender to cut the butter into the dry ingredients until coarse, crumbly pieces form. The mixture should resemble wet sand.
Small tip: Using cold butter is crucial for creating a perfectly crumbly topping.
-
Step 6: Add the Topping
Evenly sprinkle the pecan crumble mixture over the sweet potato base in the baking dish. If you plan to use marshmallows, you will add them in a later step. For a purely pecan-topped casserole, this is your final topping.
-
Step 7: Bake the Casserole
Place the baking dish in the preheated oven. Bake for 25-30 minutes, or until the sweet potato mixture is set and the pecan crumble topping is beautifully golden brown. The edges should be slightly bubbly.
Small tip: If the topping starts to brown too quickly, you can loosely tent the dish with aluminum foil.
